Special notes on LCD monitors

The following are normal with the LCD monitor and do not indicate a problem.

• Due to the nature of the fluorescent light, the screen may flicker during

initial use. Turn off the power switch and then turn it on again to make
sure the flicker disappears.

• You may find slightly uneven brightness on the screen depending on the

desktop pattern you use.

• The LCD screen has 99.99% or more effective pixels. It may include

blemishes of 0.01% or less such as a missing pixel or a pixel lit all the time.

• Due to the nature of the LCD screen, an afterimage of the previous screen

may remain after switching the image, when the same image is displayed
for hours. In this case, the screen is recovered slowly by changing the image
or turning off the power switch for a few hours.

iv

Accessibility

Be sure that the power outlet you plug the power cord into is easily accessible
and located as close to the equipment operator as possible. When you need to
disconnect power from the equipment, be sure to unplug the power cord from
the electrical outlet.

Safe listening

To protect your hearing, follow these instructions.

• Gradually increase the volume until you can hear it clearly and comfortably

and without distortion.

• After setting the volume level, do not increase it after your ears have

adjusted.

• Limit the amount of time listening to music at high volume.

• Avoid turning up the volume to block out noisy surroundings.

• Turn the volume down if you can't hear people speaking near you.

• Do not place this product on an unstable cart, stand or table. If the product

falls, it could be seriously damaged.

• Slots and openings are provided for ventilation to ensure reliable

operation of the product and to protect it from overheating. These
openings must not be blocked or covered. The openings should never be
blocked by placing the product on a bed, sofa, rug or other similar surface.
This product should never be placed near or over a radiator or heat
register, or in a built-in installation unless proper ventilation is provided.

• Never push objects of any kind into this product through cabinet slots as

they may touch dangerous voltage points or short-out parts that could
result in a fire or electric shock. Never spill liquid of any kind onto or into
the product.

• To avoid damage of internal components and to prevent battery leakage,

LCD pixel statement

The LCD unit is produced with high-precision manufacturing techniques.
Nevertheless, some pixels may occasionally misfire or appear as black or
red dots. This has no effect on the recorded image and does not constitute
a malfunction.

ENERGY STAR (for selected models) is a government program (public/private
partnership) that gives people the power to protect the environment in a cost
effective way and without sacrificing quality or product features. Products that
earn the ENERGY STAR prevent greenhouse gas emissions by meeting strict
energy efficiency guidelines set by the US Environmental Protection Agency

Tips and information for comfortable use

Computer users may complain of eyestrain and headaches after prolonged use.
Users are also at risk of physical injury after long hours of working in front of a
computer. Long work periods, bad posture, poor work habits, stress,
inadequate working conditions, personal health and other factors greatly
increase the risk of physical injury.

Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis,
tenosynovitis or other musculoskeletal disorders. The following symptoms may
appear in the hands, wrists, arms, shoulders, neck or back:

• numbness, or a burning or tingling sensation

• aching, soreness or tenderness

• pain, swelling or throbbing

• stiffness or tightness

• coldness or weakness

If you have these symptoms, or any other recurring or persistent discomfort
and/or pain related to computer use, consult a physician immediately and
inform your company's health and safety department.

The following section provides tips for more comfortable computer use.

Finding your comfort zone

Find your comfort zone by adjusting the viewing angle of the monitor, using a
footrest, or raising your sitting height to achieve maximum comfort. Observe
the following tips:

• refrain from staying too long in one fixed posture

• avoid slouching forward and/or leaning backward

• stand up and walk around regularly to remove the strain on your leg

muscles

Taking care of your vision

Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive
room lighting, poorly focused screens, very small typefaces and low-contrast
displays could stress your eyes. The following sections provide suggestions on
how to reduce eyestrain.

Eyes

• Rest your eyes frequently.

• Give your eyes regular breaks by looking away from the monitor and

focusing on a distant point.

• Blink frequently to keep your eyes from drying out.

Display

• Keep your display clean.

• Keep your head at a higher level than the top edge of the display so your

eyes point downward when looking at the middle of the display.

• Adjust the display brightness and/or contrast to a comfortable level for

enhanced text readability and graphics clarity.

• Eliminate glare and reflections by:

• placing your display in such a way that the side faces the window or

any light source

• minimizing room light by using drapes, shades or blinds

• using a task light

• changing the display's viewing angle

• using a glare-reduction filter

• using a display visor, such as a piece of cardboard extended from the

display's top front edge

• Avoid adjusting your display to an awkward viewing angle.

• Avoid looking at bright light sources, such as open windows, for extended

periods of time.

ix

Developing good work habits

Develop the following work habits to make your computer use more relaxing
and productive:

• Take short breaks regularly and often.

• Perform some stretching exercises.

• Breathe fresh air as often as possible.

• Exercise regularly and maintain a healthy body.

Congratulations!

Attaching/removing the base

Attaching:
Align the release button on the
bottom of the monitor with the
corresponding slots on the bottom of
the base.

Removing:
Press the release button as

indicated, then pull in the direction
of the arrow to remove the base.

Screen position adjustment

To optimize the viewing position, you can adjust the monitor tilt by using
both of your hands to hold the edges of the monitor as shown below.
The monitor can be adjusted to 15 degrees up or 5 degrees down.

English

Connecting the power cord

• Check first to make sure that the power cord you use is the correct type

required for your area.

• The monitor has a universal power supply that allows operation in either

100/120 V AC or 220/240 V AC voltage area. No user-adjustment is
required.

• Plug one end of the power cord to the AC inlet, and plug the other end

into an AC outlet.

• For units using 120 V AC:

Use a UL-listed cord set, type SVT wire and plug rated 10 A/125 V.

• For units using 220/240 V AC:

Use a cord set consisting of H05VV-F cord and plug rated 10 A/250 V. The
cord set should have the appropriate safety approvals for the country in
which the equipment will be installed.

Power saving

The monitor will be switched to "power saving" mode by the control signal
from the display controller, as indicated by the amber-colored power LED.

Mode LED light

On Blue

Power saving Amber

3

The power saving mode will be kept until a control signal has been detected or
the keyboard or mouse is activated. The recovery time from "power saving"
mode back to "on" is around 3 seconds.

Display Data Channel (DDC)

To make installation easier, so long as your system supports the DDC protocol,
the monitor is able to plug-and-play. The DDC is a communication protocol
through which the monitor automatically informs the host system about its
capabilities; for example, supported resolutions and corresponding timing. The
monitor supports the DDC2B standard.
